To a/ZZ whom it nza/y concerm 4 .l

Be it known that we, GEORGE C. WILLIAMS the borough of Brooklyn, New York-city,` State of New York, have invented certainl new and useful Improvements in lBoWedNurf.

sery Window-Guards, of which the following isaspeeiteation. Y p

Our invention relates to bowed nursery window-guards of wire-netting, such as arev detachably connected tothe window-casing; and it consists of improved construction of' such guards extensibly for adapting them to' windows of dierentwidths, as hereinafter described, reference being made to the'accompanying drawings, in which l Figure l is an elevation .of our improved' extensible guard applied to a windowand as' seen from the outside. of the top bar of the frame. elevation of part ofthe top bar of the frame enlarged for greater clearness. Fig. 4.- is a transverse section or' the top bar on the line 4 l of Fig. 2, also enlarged. Fig. 5 is a plan view of part of the .lower frame-bar. Fig. 6 is a front elevation of the part ofthe lower frame-bar shown in Fig. 5.

Two horizontal bow-shaped frame-bars A and B are used, which, together with the vertical connectiugandsupportingrods a,mainly constitute the frame on which the inclosing protective web of wire-netting b is applied. The upper frame-bar comprises a middle main part c, two end sections d, and twofcoupling'-` pieces e, all being of channel form in crosssection, the channel being in the under side,/ as shown in Fig. 4. The middle part c is 'a straight bar, the coupling parts e are of elbow form, and the end sections dare also straight bars, preferably; but they may be curved horizontally, if desired. The bar c laps` at each end in the channels ot' coupling-sections e at one end and are riveted fast at g. The bars d lapin the channels of the other ends of couplingse and are pivoted at h, so as to have slight lateral play. At their other ends said bars d have air; eye by which they are' dow-frame 7l by eye-screws, as at j, and by rying widths.

wo'ddlscrews, as at k, or any other approved'p' .i n

means. I 1 l In the channels of Vthe respective parts of the upper bar A a strong wire l is placed and ,secured at intervals vby hooks m), riveted in the middle sections ol thechannel parts, said wire being. suitably bent ink the angles of the elbow-sections e to serve as stideners to the I bow-angles of theltrameand preventtoo free flexure at said ia'ngles, where only suiiicient flexure is required for adj ustmentof the bow .of-parts e' are relied on to positively limit the play-of .parts d against excessivemovement. The upper edge of thejnetting b is interwoven v, with other hooksorrings o, carried on wire lgfor connection'v5`vith the upper frame-bar.

Fig. 2 is a' plan view.

Fig. 3 is a frontv The lower. bow-shaped. frame-bar B comprises a middle straight rod p and two lateral arms q of like character, which are suitably flattened and riveted together at the angles of the bow, as shown at s, with slight allowance for articulation in adj nsting the extremities of the frame tothe dierent windows of va- The lower edge of the web b is woven onto these rods in the usual manner.

Such bowed guards enable a wi udow-cleaner to reach the outside of the window conveniently without removing; them.

,What we claim as ourj'invention is l. In an adjustable wire-netting bowed nursery window-guard, the combination with the upper bow-frame comprising the middle inverted channel-bar, inverted elbow channel parts lappedand riveted at one end to the ends of themiddle bar respectively, and invertedchannelend bars pivoted in the other ends of the elbow parts; .of ythe supportingrods adapted to be attached to the windowfrarne. saidnd bars andsupporting-rods con "nected bysaid rods being inserted in eyes of the end bars.

' 2. In an adjustable wire-netting bowed nursery Window-guard, the combination with the upper bow frame-barcoinprising the middle .inverted channel-bar,.invertedy elbow chan-- nel parts lappedand riveted atene end to the ends of the middle bar respectively, and inverted, channel end bars pivoted in the other ends ofthe fr'arne within Iaboutsuch'limits as g indicated in Fig. A2A jot the drawings. The terminals nfot the sidewalls of .thechannels ICO sery window-guard, the combination with the ends of the elbow parts; of the supportingrods adapted to be attached to the windowframe and connected to the ends of said chan nel end bas, the continuous wire placed in the channels of the several parts of the framebar, and secured to the respective parts at intervals along the middle of the channels,

'and the wire-netting interwoven along the upper edge with said wire;

3. In an adjustable wire-netting bowednurupper bow frame-bar comprising the middle inverted channel-bar, inverted elbow channel parts lapped and riveted at one end to the ends of the middle bar respectively, and inverted channel end bars pivoted in the other ends of the elbow parts, of the supportingrods adapted to be yattached to the window- GEO.
